Unity使用DOTween实现金币飞入效果
1 public GameObject showRewardPanel; 2 public Text SetCoinText; 3 public Text SetLevelText;//经验exp 4 private int getCoin; 5 private int getExp; 6 public Image coinImage; 7 public Image targetImage; 8 public Camera mainCamera; 9 public TextMesh coinNumTextMesh; 10 public TextMesh coinNumShadeTextMesh; 11 12 13 14 //根据获得的金币数，生成相应的预制体，展示动画效果 15 for (int i = 0; i < getCoin; i++) 16 { 17 Vector3 startPosition = coinImage.rectTransform.position + new Vector3(i * 50f, 0, 0); 18 Image newCoinImage = Instantiate(coinImage, coinImage.transform.parent); 19 newCoinImage.rectTransform.position = startPosition; 20 newCoinImage.rectTransform.localScale = coinImage.rectTransform.localScale; 21 Vector3 targetPosition = targetImage.transform.position; 22 Vector3 screenPosition = mainCamera.WorldToScreenPoint(targetPosition); 23 Vector3 scatterPosition = startPosition + new Vector3(0, UnityEngine.Random.Range(-200f, 200f), 0); 24 25 newCoinImage.rectTransform.DOMove(scatterPosition, 0.6f) 26 .SetEase(Ease.OutQuad) 27 .OnComplete(() => 28 { 29 newCoinImage.rectTransform.DOMove(screenPosition, 0.7f) 30 .SetEase(Ease.InOutQuad) 31 .OnComplete(() => 32 { 33 coinNumTextMesh.text = UserSave.coins.ToString(); 34 coinNumShadeTextMesh.text = UserSave.coins.ToString(); 35 }); 36 }); 37 }
这段代码种，coinImgae相当于金币的预制体（仅仅是相当于，因为它只是一个图片，2D游戏中也不只需要一个图片即可）。
代码的总体思路是，获取起始位置，即coinImage的位置，在这个位置生成更多的金币Imgae，再获取我们金币栏的位置，即终点位置，然后我们使用DOTween插件的DOMove函数进行移动，对于DOTween插件，这里不做详细的介绍，感兴趣的可以去了解一下，这是个很好用的2D动画插件。
